STATEN ISLAND, N.Y. -- For a thirst-quenching, homemade juice, scout out super sweet fruits such as watermelon, pineapple, mango or papaya. Put the flesh into a blender or food processor. Add cold water so as to submerge the fruit completely. Add a bit of granulated sugar or agave syrup to jack up the sweetness. Blend for about 2 minutes. Pour the liquid through a strainer. Serve over crushed ice.
